OPERATING MECHANISM' FOR SHOE-NAILING MACHINES.

Specification of Letters Patent.

Patented May 9, 1916.

Application filed April 5, 1915. Serial No. 19,195.

To all whom it may concern Be it known that I, MAURICE S. FINCH, acitizen of the United States, residing at St. Joseph, in the county ofBuchanan and State of Missouri, have invented certain new and usefulImprovements in Operating Mechanism for Shoe-Nailing Machines, of whichthe following is a specification.

My invention relates to a mechanical movement for actuating the nailingmechanism in shoe machinery and its particular object is to providesuitable interchangeable mechanism whereby the various operations may beperformed either by a manually operated foot-lever or by a suitablemotor.

An object of my invention is to construct a mechanism that will not,when being operated by one motive power, disturb or actuate the othermechanism which during said operation will remain dead.

Other objects of my invention are to construct the device in as simple amanner as possible, so that it will be easy to operate and effective inits operation, and which is economical to manufacture.

These objects I prefer to accomplish by the means and in the mannerhereinafter fully described and as more particularly pointed out in theclaims, reference being had to the accompanying drawings in which apreferred embodiment of my invention is illustrated and in which similarreference characters are employed to designate the same parts in thevarious figures.

In the drawings: Figure 1 is a vertical side elevation of my inventionapplied to a shoe-nailing machine, having the adjacent wall of thestandard broken away and having the nailing mechanism and anvil removed;Fig. 2 is a similar view showing the relative positions of the partswhen the foot lever is depressed; Fig. 3 is a view similar to Fig. 1showing the relative positions of the parts when actuated through themedium of a motor or power shaft; Fig. 4 is a vertical side elevation ofthe clutch mechanism for connecting or disconnecting the cam shaft andthe motor; Fig. 5 is a frag-- mentary end elevation of the parts asdisclosed in Fig. 1 of the drawings; Fig. 6 is a detail side elevationof the cam and cooperating mechanism drawn to an enlarged scale, andFig. 7 is a transverse section thereof taken on line 77 of Fig. 6.

Referring to the drawings it will be seen that A represents the usualstandard that is preferably a hollow elongated casting of rectangularcross section that is provided with a basal flange B at its lower endand has vertically disposed hollow extensions C and D arising from itsupper end in which suitable bearings are provided for the ournaling ofthe upper ends of the main actuating rod or shaft E and anvil rod F. Themechanism for actuating the anvil and anvil rod are fully described andclaimed in a co-pending application for Letters Patent of the UnitedStates therefor, filed even date herewith (#19,196) and therefore neednot be described in the present application.

At about its center of height the standard is provided with bearings fora suitable camshaft 10 that derives its motion from any suitable sourcesuch as a motor or belt and pulley (not shown) through the medium of adrive-shaft 11 and clutch 12. Said clutch may be of any desired type andis adapted to connect or disconnect the aforesaid shafts upon a pullbeing exerted on connecting rod 13 connected at its upper end to theproper clutch actuating member and at its lower end connected to a foottreadle 14 pivotally fulcrumed upon the wall of said standard A.

The shaft 10 is provided between its bearings with a suitable cam 15that comprises a circular disk eccentrically mounted thereon and adaptedwhen said shaft is rotated to actuate the main rod or shaft E throughthe intermediaries hereinafter described. The lower end of rod Eterminates in a plane a slight distance above the plane of thehorizontal axis of cam shaft 10 and has a substantially rectangularshaped connecting link 16 secured thereto that is provided with avertically elongated slot 17 in its central portion through which saidshaft passes transversely. At its upper end the connecting link 16 isprovided with a rounded hollow stub 18 that forms a socket into whichthe lower end of rod E is adapted to be inserted and secured, while itslower end is provided with a pendent socket 19 into which the upper endof a short rod 20 is likewise inserted and secured. The rod 20 which isreciprocably mounted in a bearing 21 forms practically an extension orcontinuation of the upper, operating rod E through the medium of theirconnections with the link 16.

Suitable parallel grooved runners 22, are slidably mounted upon thelongitudinal vertical side edges or tenons of the link 16 and areconnected across the face of said link by horizontally disposedrelatively wide strips 23 and 24 that respectively connect the upper andlower ends of said runners and afford bearing surfaces engaged by thecam 15.

A suitable substantially inverted U-shaped cross-arm 25 is boltedtransversely to the pendent socket 19 and the outer ends of the arms ofthe same are connected by means of coiled contraction springs 26 to pins27 projecting laterally from the upper ends of runners 22. The tensionof the springs 26 causes the cross arm 25 and link 16 to be keptnormally pulled upwardly to the limit of its movement so that thelateral lug 28 bears against the underside of cross strip 24. When theshaft 10 is rotated cam 15 will engage the upper surface of saidcross-strip 24 and move the entire mechanism downwardly as illustratedin Fig. 3 of the drawings. Upon the upward movement of the cam theunderside of strip 23 will be engaged thereby and the entire mechanismwill be lifted, the result of which is that the rod E is reciprocatedsufficiently to operate the nailing and other elements upon the upperend thereof.

In the use of this machine it may not always be found desirable norconvenient to employ motive power to operate it and to take care of suchcontingency I have provided means for operating the mechanism manuallyas by a foot lever. To this end I have shown a suitable lever or treadle30 pivoted at one end between suitable ears 31 on the lower portion ofthe standard and having its opposite end extended through a slottedopening 32 in said standard. Said lever is kept normally at the upperend of its movement by a coiled contraction spring 33 that is connectedthereto at one end and has its opposite end secured to the adjacent wallof the standard. This lever preferably passes transversely across thestandard immediately below and in alinement with rod 20 and in axialalinement with said rod it is provided with an elongated vertical slot34. Suitable parallel links 35 have their upper ends connected to saidrod 20 and their lower ends are connected together by a cross pin 36that passes through the slot 34 in said lever 30 and when in normalposition said pin will be in engagement with the upper end of said slot.When the mechanism is operating.

from motive power and the cam forces the parts downwardly the pin 36connecting the links 35 will move downwardly in the slot 34 toward thelower end thereof and will move to its normal position when the reversemovement takes place. However, when the machine is operated manually thedepression of the foot lever will pull short rod 20, link 16 and rod Edownwardly against the tension of springs 26, and shaft 10 beingstationary the slot 17 in the link will permit the latter to movedownwardly a distance corresponding withthe movement given said partswhen actuated by the cam and be drawn back to normal position by thesprings 26.
